When students encounter material for the first time, it is helpful if they can talk it out with a peer or teacher. This might be in the form of dealing with a vocabulary word, a scientific concept, a math problem, or a verb tense in a world language. The verbal processing that takes place in conversation with a trusted peer or teacher settles the learner, provides an opportunity to try out the language associated with the new topic, and arms him or her with confidence. Through trial, error, and immediate feedback, the student now feels more confident setting out on his or her own to tackle the topic.
